' WINDOW-CLEANING ATTACHMENT.

To. all whom it may concern:

of the latter, and'acts to remove all vapor or other substance which may have collected thereon and which would obstruct the view of the motorman therethrough.

The objects of the present invention are,

to construct a device which will be extremely cheap of construction; which will not require any complicated mechanism to operate 1 which can be installed without disfigurlng-or changing any portion of the car body; which can be readily -thrown'into and out of service; and whiclrwill be sufficiently rigid to withstand the rough usage to which 'it will be subjected, without impairing its utility in anydegree. I

The invention consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings, Figure l is a vertical section through a portion of the front of a car body, showing the device in operative position thereon; Fig. 2, a front elevation of the car body, with the device in position thereon; Fig. 3, an enlarged detail, showing the Window in closed position, in full lines, and in position to be lowered, in dotted "lines, and showing infull and dotted lines the relation of-the squeegee to the window shown in Fig.2; and Fig. 5,

when the window is in-either position; Fig. 4, a perspective of the parts in the position a View similar to Fig. 3, showing the frame thrown into position to carry the squeegee out of operative position.

' As shown in Fig. 1, the device is applied to a window 5 in the front of. the carbody 6. The window shown is of the construction generally employed in cars of modern type, and consists of a window sash 7 held against movement by a hinged shelf or ledge Specification of Letters Patent.

8 which impinges against the lower rail 9 thereof, the upper frame 10 of the sash resting against the upper rail 11 of the window casing. 'l he window travels within a guideway 12, and when lowered recedes into a chamber 13 formed in the front of the .car body. The construction and operation of windows of this class areso well known to' every one familiar with car construction that a detailed explanation is not considered essential in regard to it.

The window cleaning .device, as shown, is positioned upon a ledge 14 extending out from the front of the car, and the device is composed of a squeegee member 15 formed preferably of rubber, and carried bya squeegee frame 16 formedof Wood or other suitable material, and having a recess in its upper edge in which the squeegee member 1s inserted. The lower edge of the squeegee frame is rounded, and is cut away at intervals, as at 17, to receive lugs 18 formed on a plate 19 attached to the ledges 14. Ex-

tending through the lower end of the frame 1 A and through the lugs 18 is a pin 20, the frame and fixed plate, when joined together, forming, in effect, a hinge, in the movable part of which the squeegee member is carried. Attached to the ledge 14, at points adjacent to the sides of the fixed plate 19, are flat springs 21 which bear against pins 22 affixed in the'sides of the frame. By referring to Fig. 4, it will be seen that, with the parts 'in' the posit-ion therein shown, a

sprlng tension will be exerted against the frame 1n a directlon to hold the squeegee member in lmplngement agalnst the WITH dow, and that, with the parts as shown in' Y Fig. 5, where the frame is folded back onto the fixed plate and away from engagement with the window, the spring will exert a pressure tending to maintain it in such position. As there are a great variety of well known means for creating a spring tension which will exert itself in opposite directions as the member on which it acts is thrown pastits center, I do not desire in any way to limit my invention to a construction in which is employed a spring of the form shown;

The operation is as follows: Upon days when the climatic conditions are such as to cause a vapor tocollect upon the window and obstruct the view ofv-the motorman therethrough, he will, upon leaving the barn, or at a time during the trip when it becomes necessary, throw the squeegee intothe position shown in Fig. 4, and thereafter every time the window is lowered or raised the squeegee member will act to remove any vapor or other" objectionable substance which has accumulated thereon. The squeegee will act during both the upward and downward movements of the window, therei by effectively removing all objectionable substance therefrom, and at the same time all thewater which will necessarily accumulate around the squeegee member after it has been passed over the surface of the window will not be collected at the bottom or top of the window sash, where in either case it would be objectionable. As the squeegee strikes the upper rail of the window sash, the greater portion of the dirt and water will be thrown back over the squeegee, and the portion that remains will beremoved when the window is raised, and

, in .this manner no objectionable amount of moisture will remain at the top of the window and trickle down as the window is moved up, and no'objectionable amount of moisture willaccumulate at the bottom of .the window and from there pass into the car body around the openings which exist between the window casing and the window sash.- It will be understood that upon days when it is not necessary to use the cleaning device the frame may be thrown back into the position shown in Fig. 5, and the squeegee member retracted from operative position with the window.

When in either operative or non-operative position, the window cleaning device will not interfere in any way with the usual operation of the window, and ab during the trip the motormanjmust necessarily often lower and raise the window for the purpose of throwing switches, etc., in the majority of cases no unnecessary movement of the window will be required to keep it free from vapor or other objectionable substance.

-When the device is thrown into operative position, it will lie so as to form a weather strip for the lower sash of the'window, preventing rain, snow, or wind from penetrat' ing therethrou h/ When the. evice' is a%plied.-to certain formspf windows, it will effound that the movement" of the squeegee in' toward the window will be suificient so that the end of the frame will extend far enough beyond its. pivotal pointthat the pressure upon the squeegee incident, to the downward motion of the'window willmaintain the-squeegee member in engagement, with the window; and in this case the spring described 1n the \construction would, of course, not be necessary.

I claim:

1. In a window cleaning attachment, the.65 combination of a squeegee, comprising a squeegee member carried by. a I squeegee frame, the frame remaining in fixed position with respect to the -movements of the window, and *a mounting for'the squeegee consisting solely of a single fixed plate in which the squeegee frame is pivotally secured, substantially as described.

2. In a wlndow cleaning attachment, the combmation of a squeegee, comprising a squeegee member carried by a squeegee;

frame, the frame remaining in fixed position with respect to the movements of the; window, a fixed plate in which the squeegee frameis mounted, and means for holding the frame into andout of operative position with the window, consisting wholly of a tension member, substantially as described.

3. In a window cleaning attachment, the combination of a squeegee, comprising a squeegee member carriedby a squeegee frame, the frame remaining in fixed position with respect to the movements of the 'window, and a mounting for the squeegee frame consisting solely. of a plate extending across and affixed to the window ledge, in which the squeegee frame is pivot-ally secured, substantially as described. I

4:. In a window cleaning attachment, the combination of a squeegee, comprising a squeegee member carried by a squeegee frame, the framebeing in the form of a hinge, and consisting solely bf two leaves one leaf being attached to the window casing and the other leaf lying freeand'carry- 1 ing the squeegee member, substantially as described. i

'5. In a window cleaningiattachment, thecombination of a squeegee, comprising asqueegee member carried by a squeegee frame, the frame being in the form of ahinge, having one leaf attached to the window casing and the other leaf lying free and carrying the squeegee member, and a v tension member bearing against the free leaf and serving to maintain the leaves in distended or folded position, substantially as describ.ed.- v
